Bug#869093: mpv: hwdec=vdpau now not supported?

[Arthur Marsh]

Package: mpv
Version: 0.26.0-1
Severity: normal

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

Replaying a video that on the previous version of mpv used minimal cpu:

$ mpv --vo=vdpau --hwdec=vdpau *mp4
Playing: blah.mp4
 (+) Video --vid=1 (*) (h264 1920x1080 29.970fps)
 (+) Audio --aid=1 --alang=jpn (*) (aac 2ch 48000Hz)
     Audio --aid=2 --alang=jpn (*) (aac 6ch 48000Hz)
     Audio --aid=3 --alang=jpn (*) (aac 2ch 48000Hz)
Requested hardware decoder not compiled.
AO: [pulse] 48000Hz stereo 2ch float
VO: [vdpau] 1920x1080 yuv420p

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

I checked the release notes, which stated:

VA-API/VDPAU hardware decoding now requires FFmpeg > 3.2.

and checked the installed ffmpeg:

ffmpeg         7:3.2.6-1+b3

   * What was the outcome of this action?
   * What outcome did you expect instead?

Since I had ffmpeg installed from Debian, I expected vdpau support to work,
which apparently didn't. 
(vdpau support did work in vlc, with low cpu consumption).
